Description
Technical field
The present invention relates to a kind of infusion pump, particularly a kind of cover pole type micro pump that is applied on the household electric appliance such as washing machine, dishwasher.
Technical background
Patent application 200510038506.2 discloses a kind of " mini-sized shaded pole type water-drainage pump ", comprise coiling assembly, stator iron core, electric machine casing, pump case and axle center assembly, the axle center assembly is integral p-m rotor, coupling, bearing support, impeller sets by motor shaft, impeller inserts in the coupling endoporus by its tubular axis, because impeller tubular axis top end has the spring sheet of projection, spring sheet is fallen within the pit in the coupling endoporus form self-locking, make on-stream unlikely the coming off of impeller, this mode has good self-locking effect, but shows loaded down with trivial details in the part making slightly; Behind the long-play, blocked by foreign matter in addition, will make the motor internal temperature be increased to material deformation, water pump is lost cause after the effect and scrap in case run into impeller.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, a kind of improved miniature shaded pole type water pump is provided, the evenly spaced fan post of coupling is pressed in the gap of being separated by projection in the impeller axis hole, because the barb on fan post surface forms the retaining effect, make coupling and impeller produce self-locking action, impeller can not come off, the design is simple in structure, noise is low, low cost of manufacture, specifically implement like this: improved miniature shaded pole type water pump, comprise the coiling assembly, stator iron core, electric machine casing, rear bearing, pump case and axle center assembly, the axle center assembly by motor shaft with p-m rotor, coupling, bearing support, impeller sets is integral, it is characterized in that coupling runs through bearing support, the sleeve pipe that one side is provided with eccentric link stopper is installed on the coupling of p-m rotor end, described casing shoe face have one with eccentric link stopper all-in-one-piece evagination platform be overlying on the p-m rotor exterior edge face; The coupling of impeller end is surrounded by evenly spaced two to four fan posts, and the fan outer surface of column is equipped with barb; Impeller is made of blade, base, axis hole, and shaft hole inner wall is provided with the spacer block that connects with coupling fan intercolumniation crack.During coupling socket impeller, only need that coupling is fanned post and be pressed between projection in the impeller axis hole, be pressed into the back because fan post surface is equipped with barb, and barb tightly hooks and fan the impeller shaft hole inner wall that post connects, thereby guarantee that impeller in use can not come off.
Electric machine casing of the present invention center is provided with the tubulose endoporus of placing p-m rotor, the bottom and the upper periphery of tubulose endoporus are provided with aqua storage tank, before pump working, water is promptly arranged in the aqua storage tank, the heat in the machine operation running can be obviously evacuated in the existence of water, its inside temperature is unlikely too high even motor works long hours, even plastic tube-shape can not produce distortion, thereby makes the stall destructive test considerably beyond like product.In order to strengthen the intensity of equipment, be provided with the reinforcement dividing plate of similar stiffening rib shape in the aqua storage tank.
The magnetic post of p-m rotor is coated with a plastic layer and extension has a plastic cylinder in the assembly of axle center of the present invention, and described plastic cylinder inwall is provided with an eccentric block, and the eccentric block on this block and the coupling sleeve pipe rotates pairing.Pump motor get electric after, p-m rotor turns round on motor shaft, because the pair relationhip of p-m rotor and coupling sleeve pipe drives coupling and impeller rotates.In order to reduce the friction collision between the eccentric block of eccentric block and sleeve pipe, respectively be equipped with a buffering software post (as rubber column) in the block both sides of p-m rotor, reduced running noise thus.
Be equipped with bearing sleeve in the axis hole of bearing support of the present invention, bearing sleeve can be that metal is made, and also can be that nonmetallic material are made, if adopt the nonmetallic bearing lining, establishes a metallic shim in addition between coupling and nonmetallic bearing lining.The setting of bearing sleeve and metallic shim has reduced vertically with radially rubbing of coupling.
Be equipped with the protruding circle concentric on the impeller face bearing support of the present invention with axis hole, protruding circle inboard is provided with inwardly protruded muscle, the pit that constitutes between protruding circle and axis hole is built-in with bowl-type circle inserts, is filled with Sealing between bowl-type circle inserts and bearing sleeve, and Sealing endoporus aperture is slightly less than coupling axis hole external diameter.Because the effect of the inboard muscle of protruding circle, push down Sealing and bearing sleeve simultaneously after making bowl-type circle inserts be pressed into the pit of bearing support.When turning round in the endoporus of coupling at bearing sleeve, having slowed down running vibration, reduced noise, the water that Sealing makes coupling inside is outside seepage not.
The bearing support of p-m rotor face of the present invention is provided with an annular boss concentric with the bearing support axis hole, pit concentric on annular boss and the electric machine casing docks setting-in, the bearing support peripheral surface of this face is made of inclined-plane and step, elastic seal ring on the inboard corresponding step in step and electric machine casing edge amplexiforms, the peripheral planar limit of impeller face bearing support is fixed by pump case, this concentric structure can be guaranteed the coaxality of axial portions, finishes concentric running.
The present invention is by the self-locking structure of impeller and coupling, rotates in any case, and working time how long, impeller all can not come off, again by the effect of aqua storage tank water in the electric machine casing, make and can not heat up too highly in the equipment operation, guarantee that component can not be out of shape because of being heated, this compact equipment, processing technology is simple, and cost is low, and noise is few, designed reliability is good, is applied to have the irreplaceable advantage of prior art on the household electric appliance such as washing machine, dishwasher.
